在1993年1～5月期间,来自独联体的海绵钛戏剧性地大量拥入美国市场;但是,美国工业界的消息灵通人士宣称,他们并不恐慌,也未看到什么坏兆头.据认为,目前有两道屏障在限制从独联体进口海绵钛:一是反倾销的高关税;二是对使用独联体材料的固有限制.美国进口的海绵钛仍然主要来自日本和西欧.在美国,针对来自亚美尼亚、阿塞拜疆、爱沙尼亚、格鲁吉亚、哈萨克斯坦、吉尔吉斯、拉托维亚、立陶宛、俄罗斯、塔吉克斯坦、土库曼斯坦、乌克兰和乌兹别克斯坦的反倾销决定现在继续有效. During the period from January to May 1993, the titanium sponges from the Commonwealth of Independent States were dramatically crowded into the U.S. market; however, the U.S. industry’s well-informed sources claimed that they did not panic and did not see any bad news. Currently, there are two barriers in restricting the import of Sponge Titanium from the Commonwealth of Independent States: one is the high tariffs of anti-dumping; the second is the inherent restrictions on the use of CIS materials. The United States imports sponge titanium still mainly from Japan and Western Europe. In the United States, Anti-dumping decisions against Armenia, Azerbaijan, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Russia, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan are now still effective.
